Q R S T and U character pattern programs in Java

1.  Character Pattern Q in Java

In this article we study how to display character pattern Q in Java programming language.

import java.util.*;
class Q
{
  public static void main(String[] args) 
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(i==j&&i>=n/2||(i==0||i==3*(n/4))&&(j>0&&j<3*(n/4))||(j==0||j==3*(n/4))&&(i>0&&i<3*(n/4)))//if(i==j&&i>=n/2||j==0&&i>0&&i<n-1||

i==0&&j>0&&j<=3*(n/4)||j==n-2&&i>0&&i<=3*(n/4)||j>0&&j<=3*(n/4)&&i==n-2)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

Output of pattern Q in java

2.  Character Pattern R in Java

In this article we study how to print character pattern R in Java programming language.

import java.util.*;
class R
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==n/2&&j>=0||i==0&&j>=0||j==n-1&&i<=n/2||i>=sn/2&&i==j)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

3.  Character Pattern T in Java

In this article we demonstrate how to display character pattern T in Java programming language.

import java.util.*;
class T
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(i==0&&j<=n||j==n/2&&i>=0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

4.  Character Pattern U in Java

In this article we demonstrate how to print character pattern U in Java programming language.

import java.util.*;
class U
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==n-1&&j>=0||j==n-1&&i>=0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}
